| Methods/Experimental Design: |
Sampling: water samples taken weekly
(biweekly during 1979-1980) from the stream just above weir (at the same
site other samples for
chemical analysis are taken). Samples taken in pre-combusted glass
bottles and kept refrigerated. | Filtering: water filtered when samples are returned to lab. Filtered through pre-combusted Gelman A/E glass fiber filters. DOC: from July 1979 through July 1985, samples were analyzed in a Dohrman DC 80, which uses UV catalysis in the presence of persulfate to convert DOC to CO2, then reduces CO2 to methane, and analysis for methane. | From August 1985 to October 2002, samples analyzed on Oceanography International Carbon Analyzer (MODEL 700) which uses persulfate oxidation at 100C and Analyses for CO2 evolved. All analyses have been done at the lab in Athens. |
